New for 2012, the MRF line from ECHO 1 look like something you would expect to see come from of a high end pro shop. Tricked out with a free floating MRF rail system and flip up battle sights these highly detailed M4 series rifles are officially licensed by Troy Industries with full trademarks. Each rifle is equipped with a six position collapsible crane stock which houses a nun-chuck type battery thus eliminating the need for an external battery box and maintaining the rifles low drag, high speed profile.

Like most of the other ECHO 1 rifles, the MRF series uses a lightweight yet durable polymer receiver although the rest of the rifle is constructed out of metal to include its MRF rail system. Its flip up battle sights are also some of the best we have seen on an ECHO 1 rifle to date and have a positive locking mechanism which keeps them from getting knocked down if they rub against underbrush or tree branches.

Internally the rifles have a brand new Version 2 gearbox which has an impressive list of features.

Steel gears on 8mm sealed bearing bushings.

Steel core spring guide with bearing.

Ported polycarb piston head with bearing.

Polished chrome cylinder.

Polycarb piston with second to last tooth removed.

Reinforced gearbox shell.

High torque motor.

On the firing line these rifles ran exceptionally smoothly with solid performance. Since they are equipped with a pretty aggressive hop-up bucking we found that you really do not want to be using anything lighter than a .25g to maintain the optimum trajectory. With Elite Force .28g BBs though we found these rifles to be extremely effective at long range and more than capable of connecting with a torso sized target from 60 yards out.

The Troy MRF-MX features a 10 inch MFR rail system and 14.5 inch barrel.

This gun, in short, is amazing. My friend bought one telling me it was amazing. I thought, "Oh well. I'll just destroy him with my Sig 556." I got into a firefight with him, and within a minute, I realized that our guns did not compare. His was the much superior weapon. Superior in speed, accuracy, rate of fire... everything. Not to waste too much time on sentiments, let's move the list form.

Pros:
10 inch free float rail (always nice for accuracy's sake)
Battery included is a 9.6 volt vs. an 8.4 (provides a very handsome rof and life)
Crane stock is of the very best quality, made of high-end polymer
Will launch a .25g bb at about 400 FPS
Iron sights included are amazing
Selector switch is definitive in selection
NO issues with the mag well; nice definitive click when mag is in
Trademarks look great
Comes stock with a Madbull hop-up bucking

Cons:
Crane stock knobs have a tendency to fall of (nothing a little tweaking won't fix)
Body is plastic... but I don't see this one ever breaking unless very much abused

Overall, I was extremely impressed with this gun. For the price, you're definitely getting a good deal. Forget the Combat Machine, I'm using this baby from now on

This gun is incredibly accurate! I can shoot a five inch circle at 150 feet.
I can accurately shoot a 10 inch circle at 200 feet.
I took five shots each for both of those targets and hit the target each time.
So besides this gun being accurate it is also powerful. I hit my brother with it five times at more than 150 feet and he has had welts for several days now because of it!

Now there is one con with this gun. And that is there are two plastic pieces that are supposed to hold the nunchuck batteries in place. Unfortunately they come out way to easily. There is a way to keep them in though. I just put super glue on the tabs and but them in. They have yet to come out again. I would recommend this gun to everyone.
